, IMPROVEMENT IN COUNTING-MACHINES.

Specification forming part of Letters Patent No. 1 L577, dated August 22, 1854.

To all whom it may concern Be it known that I, PAUL STILLMAN, of New York, in the county of New York and a State of New;York, have invented certain new and useful Improvements in Registers for Numbers which are Applicable to Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known, and of the usual manner of making, modifying, and using the same.

This improvement consists of a new construction and arrangement of the parts that turn and hold the count-wheels, by which their strength is increased and their permanence and accuracy secured.

The construction is as follows:

In the drawings, Figure 1 is a front view of the interior of the apparatus with the outside case removed. Fig. 2 is a sectional elevation of the same on line 00 m of Fig. 1. Fig. 3 is a .section in the plane of the axis of the count wheels. Fig. i is a front view of the exterior case with the count-wheels showing at the proper point for register. Figs. 5, 6, 7, and 8 are modifications of certain parts.

a is a permanent aXis,upon which the count- Wheels I) turn. These wheels are formed of a thin plate, from which a rim projects on one side, forming a broad periphery sufficient to mark the figures upon, around the face of which are made the ten Arabic or other characters, as is clearly shown in Fig. 1. The wheels I) Z) Z) 6 have projections from the edge of the rim at 0. Two arms, d, project from the axis it, upon which they freely turn, one on each side, extending beyond the periphery of the wheels, with a cross-piece, d, uniting the two. One of these arms is connected in any convenient way with the movement.

It is m tended to register so as to cause them to vibrate a proper distance. On the cross-piece (1 there is a pawl, e, that catches upon the projections 0 upon the first wheel of the series. The pawl is borne down to its place by a spiral spring, 9', surrounding the piece (1. A roller, 0 is attached to the side of the pawl to ease it over the projections. On the first wheel, I), there is a spring'catch or clutch, j, that lies back against the wheel during its revolution till it comes to the point where the second count-wheel is to move, at which time an inclined projection, f, from it strikes a stationary stile, g, and throws the clutch out so as to catch a projection upon the second wheel and move it one number, in doing which the clutch is released by passing the stile, another first wheel is thus freed so as to move round alone till it is again brought to the po sition to carry forward the second wheel another number. On the revol ution of the second wheel the third is moved one figure by the same device, and so on through the series. Each ofthe wheels has a holding clutch or pawl, h, held up to its place by a spiral spring,which are for the purpose of holding the wheels firmly in place.

Having thus fully described my improved register, what I claim therein as new, and dcsire to secure by Letters Patent, is

The employment and arrangement of the clutches, having a spring sidewise so as to catch into the facenotches, and the styles outside the count-whccls, by which they are operated to move a series of count-wheels, in the manner and for the purpose set forth.

PAUL STILLMAN.
